Description

OBJECT OF THE INVENTION

The present invention which is defended here, consists of a system conformed by several devices that allow to find an automobile or another vehicle parked in areas intended for said purpose, by means of widely used current technology, which are easy to use and do not require installing additional accessories in the vehicle.
For a better service to the user of the parking areas, it is convenient to have a device that orients and guides the user until the parking space of his/her vehicle, who does not have to worry about its location.

BACKGROUND OF THE INVENTION

In the current parking, the only existing method to locate a parked vehicle later on, It is the identification of the parking space by means of the letters and digits combination, for example J320. It must be usually completed with the number of the floor or plant and the sector inside the floor or plant, being the localization as follows: floor 3, sector Cinema, street J, parking space 320. The range of colors, is used to delimit the different parking areas.
A form to palliate this problem, is that the user takes note of the code, either memorizing, recording or registering it electronically, or writing it in any element at his/her disposal, what means that he/she will have to transport some extra element in his/her pocket.
In these places any method that is based on the Global Position System (GPS), GLONASS or similar as the next Galilean lacks usefulness, because there are some obstacles (the own building) that interfere in the satellites signs which must be received by the navigator or receiving GPS installed in the vehicle, to define the exact position in coordinates, at the moment he/she leaves it parked.
When the user wants to find his/her parked vehicle, he/she has the same inconvenience with the receiving portable GPS, where previously it was also impossible to register the localization of the parking space in question. Also this coordinates used to have a short coming of at least 40 meters, unless it arrange differential phase or the DGPS corrections.
In the market there are different optic systems and/or mechanics and/or electronic and/or electromagnetic which solve the problem in question, but their biggest inconvenience reside in the high cost of installation and maintenance, due to its complexity, sophistication and the human personnel who must be devoted to be of that service. These systems can have interferences of different characteristics which diminish their effectiveness in the supposed solution, and which can transform them in unviable or little practical. It can consider that some of them attempt against the anonymity and people's intimacy, due to the type of data that they register.
Therefore it is continued depending on not making a mistake of building, of floor or plants, sector inside the floor or plant, sense of search at the moment to find the parked vehicle, lacking a device that orients and guides him/her to the search vehicle, without it means to add accessories to the vehicle or to have to carry some extra elements in his/her pocket.
The present invention allows to save the mentioned difficulties, using current technology, daily and simple use elements, which hierarchize the areas intended for parking vehicles, for its extra service that offers to the user.
The applicant in the search carried out in the databases linked to the O.E.P.M's web page, it didn't find another system to find parked vehicles, with the characteristics of the one is going to describe after, therefore it isn't known the existence of another similar device.

EXPLANATION OF THE INVENTION

The main novelty of the invention, object of this presentation, it is based on the registration or storage of the localization of parked vehicle, in an appropriate support and its later process to be able to orient and guide the user until his/her vehicle, without getting wrong.
The cards with magnetic band or intelligent chip, it is the more spread support in this type of establishments, in order to getting paid for the time that the vehicle was parked, therefore it takes advantage of the mentioned support to store the localization, keeping up the same quantity of elements which are used at the moment and avoiding any type of added annoyance.
The system is characterized by its modular design which consists of the following components: a suitably programmed microcontroller, an audiovisual electronic alerting unit, a Smartcard connector, a bar code laser scanner, a LCD screen, a power source connected to the general net of electric fixtures, a presentation box, Smartcard, ticket-card with bar code, computer programs and flat relative cartesian coordinates, everything appropriately combine to get the objective.
The localization of the parked vehicle is defined by means of a system of flat relative cartesian coordinates, own and unique of the building or area intended for such purposed, that is materialized in the code to store. To this code is added the identification of the parking, to avoid the search in a mistaken building, also adding other data for an easy search.
A previous study of the parking, the later installation project of the invention now defended and the necessary investment, in such way that it were not a cost to the user, it will condition the quantity of each one of mentioned types posts which allow to define the localization code in relation to each parking space of itself, for its using after materializing the invention physically.
It is named “Registering Post”, to the place by means of a device registers or stores the localization code of the parked vehicle, being only used the nearest to the parking space in question, so that the later search were the correct one and “Orienting Post” to the place that by means of another device, partially different to the previous one, it gives the necessary orientation and guided to find the parked vehicle, being able to use whichever and every time that it were necessary until finding the searched place.
Once the vehicle is parked, the “Registering Post” registers or stores the localization code of the parking space, by means of the option that the parking has installed:

- a) If it is bar code it is registered in the magnetic band card by means of a stamp of automatic ink (simile Trodat), pressing it by hand or also taking away the ticket-corresponding card, from the recipient intended for such purposed. b) If it is Smartcard, it is inserted in the corresponding connector, to record the data that have to store, taking away the card after finishing the recording, the one is indicated through an audiovisual sign.

The “Registering Post” of bar code, uses the stamp of automatic ink, where the usual support of rubber is stuck, this has recorded the localization code, needing a minimum cleaning maintenance and ink pad replacement with ink, as well as the verification of the quality impression. It also uses the ticket-card deposited in a recipient that needs the corresponding replacement, which are printed by means of a normal characteristics computer and the use of an appropriate shears, for its cut, generating a hand work. The printing program ticket-card, has stored the localization codes of each parking space. The “Registering Post” of Smartcard is electronic and automatic and when detecting the insertion of the card in the Smartcard connector, it carries out the recording of the data belonging to the localization code.
The “Orienting Post” has among its devices, the suitable lector of the support used to register or store the localization code of the parked vehicle, being a completely electronic and automatic process. If the support is of bar code, it has a laser scanner with a good configurations, for the used format among its constituents, so that it is activated and read automatically before the presence inside its influence area, of the magnetic band card or the ticket-card which have registered the corresponding localization code. The “Orienting Post” for Smartcard support, has a Smartcard connector among its constituents, turning on mechanics-electronically to the microcontroller when the card is inserted in its interior and being carried out the lecturing in automatic way.
The microcontroller processes the localization code, in order to visualize in the retro-illuminated LCD screen, by means of an alphanumeric text, the information that will allow to orient and guide the user which requests it, until the searching parking space. The different informations which can be visualized, they allow us to know if the building, floor or plants and sector inside the floor or plant are the correct ones, to be able to begin the properly search, when we are in the nearest area to the searched vehicle.
In the system of flat relative cartesian coordinates, the difference in the axis “z” (vertical), will indicate the quantity of floors or plants, expressed in units which it must be up or down, to arrive at the right place. In most of the establishments intended for parking, the circulation streets inside the same have a distribution of rectangular form, having as norm the axis “x” parallel to the biggest length streets and the axis “y” parallel to the smallest length streets. When we are in the nearest area to the searched vehicle, the information that is visualized it is the following one: a) steps to walk along the street of the “Orienting Post” (axis “x”), in the indicated direction in the LCD screen and that it coincides with the distance expressed in meters (difference of coordinates axis “x”) existing between the “Orienting Post” and the normal point to the parking space in question, on the street that we are going through. b) to get to the normal point we must turn to the left or to the right, according to the result of the difference of the coordinates in the axis “y” between the mentioned normal point and the parking space in question c) steps to walk along the normal to the street of the “Orienting Post” (axis “y”), until get to the parked vehicle which was looked for, and that it coincides with the distance expressed in meters (difference of coordinates axis “y”) existing between the mentioned normal point and the parked vehicle.
The invention which is defended here, it checks the different processes, through different computer programs designed especially to such effect and which are registered in the microcontroller memory, during the installation of the system.
The computer program installed in the microcontroller, it is mainly designed to control the following processes: a) the manage of the system of flat relative Cartesian coordinate, in all the calculations that the invention carries out b) the recording and lecturing of the localization code of the parked vehicle in the Smartcard c) the data admission sent by the laser scanner, corresponding to the lecturing of the cards which register the localization code, by means of the corresponding bar code d) the visualization of the different informations in the LCD screen that they orient and guide to the user who requests it, to find his/her vehicle e) the control of audiovisual electronic alerting unit f) reset the system g) the lecturing and memorization of the “Post” coordinates h) the auto-checking of the “Post” correct initiation i) the control of the correct operation of the different devices of the system j) the control of the language change that will be used in the visualization of the informations.
In the “Orienting Post” in order to achieve a biggest universality, it is able to choose the language in which we want to visualized the informations in the LCD screen, being able to achieve this selection, pressing once the idiom button corresponding to the wanted language. For not increasing the installation costs, a space problem for the buttons and memory to have kept the text to visualize, it limits that selection to less than ten options that will allow to select the more used languages in the area where the system is installed.
The audiovisual electronic alerting unit has the function of indicating in which situation it is, the recording or the lecturing of the localization code of the parked vehicle. There is a colour visual sign and quantity of Led and an acoustic sign taken place by the loudspeaker that identifies the moment in which the microcontroller is carrying out the lecturing or recording of the mentioned data, also allowing to know easily when these processes finish by means of the different characteristics of the audiovisual sign.
The power sources that the computers use, they improve the modular design and mainly satisfy the necessities of electric power supply to the tension and strength necessary, of the different electronic constituents of the system and being connected to the domiciliary general net of electric fixtures, through their transformers.
The box or wrapping has as main function, the protection of the devices that contains inside, the execution of the electric security norms and the perfect visualization of the “Posts”, for their identification, also taking advantage of its construction in order to facilitate the system assembly, to show the logo of the product, the use guide itself, a commercial presentation of the product and others.
